Q 24. - Calculus

Question

Your calculator should be able to approximate the area between a graph and the x-axis. Determine how to do this on your particular calculator, and then, in Exercise, use the method to approximate the signed area between the graph of each function f and the x-axis on the given interval [a, b].

$f\left(x\right)=\sin x, \left[a,b\right]=\left[0,\mathrm{\pi }\right]$

Step-by-Step Solution

Answer

Answer is 1

Step 1. Given information

Function is $f\left(x\right)=\sin x, \left[a,b\right]=\left[0,\mathrm{\pi }\right]$

Step 2. Explanation

Consider the function $f\left(x\right)=\sin x$

Area $={\int }_0^{\mathrm{\pi }}\sin x$

          $$\begin{gathered} =1-0 \\ =1 \end{gathered}$$
